What is the typical time frame between first pairings and ovulation?

I began a specific pairing just a couple weeks ago directly after my female had shed. They almost immediately locked up and continued locking up throughout the week as I reintroduced the male every few days. Additionally, the female has refused the past couple meals since the pairing started. This morning I woke up to my female going blue again (just ~2.5 weeks since her last shed and no meals since), but I never really noticed any major swelling (could have missed it though). Is it possible that this is her pre-lay shed?

I was fully expecting a much longer and drawn out process of mating if she is indeed going to lay. It just is extremely odd that she is going into another shed in such short time.

Thanks!
